Electric Arc

An arc of lightning leaps from your outstretched hand towards a creature or object within range. Make a ranged spell attack against the target, dealing 1d8 lightning damage on a hit. If you hit, or if the target was a metal object, you can then make another ranged spell attack from the target's position against another creature or object within 30 feet of it. On a hit, you deal 1d8 lightning damage.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
